Former Royal Aide Reveals Mother’s Decades-Long Career in British Intelligence

Jamie Lowther-Pinkerton spent most of his life knowing little about a significant portion of his mother’s past. Sue Lowther-Pinkerton joined British intelligence agency MI5 after World War II and remained tight-lipped about her work throughout her life, rarely discussing the classified nature of her employment during the Cold War era.

The revelation came inadvertently decades ago when Sue was watching a documentary with her children about the Cambridge spy ring, a group of Soviet agents who had penetrated British institutions. When a filmmaker suggested Sir Roger Hollis, who directed MI5 from 1956 to 1965, might have been a secret Soviet operative, Sue immediately dismissed the notion without hesitation, calling him “a total gentleman and a patriot.”

Lowther-Pinkerton recalled his astonishment at his mother’s definitive response, noting he was in his mid-20s before learning about her intelligence career. He attempted to extract more details from her but found she belonged to a generation that refused to discuss classified matters, even with family members.

Before entering the secretive world of MI5, Sue had already demonstrated a spirit of adventure and service. During World War II, she worked with NAAFI vans delivering refreshments to troops and later joined the Auxiliary Territorial Service, the women’s branch of the British Army, in 1942.

She was stationed at the Royal School of Artillery at Larkhill, where she operated gun limbers transporting artillery equipment across firing ranges. The hazardous nature of this work earned her an additional four pence daily in compensation.

Sue’s intelligence work began even before formally joining MI5. Following her military discharge in 1948, she worked in Army intelligence in Singapore, where she handled classified communications regarding HMS Amethyst’s 1949 escape from China’s Yangtze River.

Upon returning to Britain in 1951, Sue commenced employment at MI5’s Leconfield House, where she maintained absolute secrecy about her duties. She left the agency in 1956 to establish a family with her husband, Anthony Hull Lowther-Pinkerton, described by their son as a gregarious Anglo-Irishman nicknamed “Rumpty.”

Sue was renowned for her composure and ability to manage household challenges with humor and grace. One memorable instance involved her hurling a roast potato down the dining table at her husband when his mood had grown particularly somber, an act of levity that restored his spirits within moments.

For nearly five decades following her departure from MI5, Sue dedicated herself to organizing the annual Poppy Appeal, a fundraising initiative benefiting veterans and active-duty military personnel. She also delivered Meals on Wheels to isolated rural residents for several decades before her death in 2023 at age 99.

Her son’s career path also intersected with British institutional life. Lowther-Pinkerton served Queen Elizabeth the Queen Mother as an equerry before becoming a private secretary to Prince William and Prince Harry from 2005 to 2013, serving as a mentor to both princes.

The royal couple later requested that Lowther-Pinkerton serve as godfather to Prince George. His son Billy participated in William and Kate’s wedding as a page.

The remarkable women in Lowther-Pinkerton’s life have profoundly shaped his creative work. His novel “Beyond the Design of Light” centers on a character named Missie, a spirited young woman who enters military intelligence, directly inspired by his mother’s extraordinary life and resilience.
